This study was performed to examine the major explanatory factors on the aspects and stage of physical activity change by applying transtheoretical model to the subjects, adults, who reside in the community, and offer basic data in developing the meditating strategies to enhance physical activity by stage of change.
The purpose of concrete study in analytical stage was to examine the followings, such as (1) the distribution of stage of physical activity change by Socio-demographic factors (2) the change in the decisional balance, self-efficacy, and process of change by stage of physical activity change (3) which factor of Socio-demographic variable, decisional balance of transtheoretical model, self-efficacy and process of change affects stage of physical activity change through multiple recurrence analysis, and (4) the applicability of transtheoretical model on the subjects, adults, of the community by implementing covariance structure analysis on the effect of decisional balance, self-efficacy, and process of change on stage of behavioral change.
With the questionnaire of 1,604 adults sampling(male and female) from the age of 30 to 64 who reside in the 3 counties of the central area in July, 2005, only 1,243 adults were targeted as final study subjects(the rate of survey completion: 77.5%). The questionnaires were distributed and surveyed by trained examiners ho visited and made the subjects report to the questionnaire after explaining about the contents.
The data analysis was implemented to examine the related factors to affect stage of change as follows;
(1) Statistical analysis was implemented using SPSS 11.0, LISREL 8.0 (2) the reliability of transtheoretical change model was approved as the value of Cronbach's α (3) the frequency analysis was implemented to examine the distribution of common characteristics, exercise-related characteristics, and the stage of exercise behavior change (4) cross-analysis was implemented to examine the distribution of stage of change according to common characteristics of the subjects (5) one-way ANOVA was implemented for the difference of process of change, decisional balance, self-efficacy according to stage of regular exercise behavior, and when there is a significant difference, Scheffe's post-hoc comparison analysis was implemented. (6) Multiple regression analysis was implemented to assort the explanation to affect stage of physical activity change.
The major results of this study are as follows;
First, when the reliability of process of exercise behavior change, decisional balance tools, self-efficacy of the concepts of transtheoretical change model was examined, it was shown, such as process of exercise behavior change(0.92), decisional balance(0.78), and self-efficacy(0.94).
Second, when examining the degree which subjects lay weight on the pros and cons of exercise according to stage of change, the average score of pros of exercise was lowest at pre-consideration stage, and followed by stages of consideration, preparation, behavior, and maintenance. The lowest score of pre-consideration stage of the above was significantly lower than that of consideration stage, and the score of the stage of consideration was lower than that of maintenance stage ((p<0.01). In the average score of cons in the exercise, the score of maintenance stage was significantly lower than that of pre-consideration stage and preparation stage, and that of behavior stage was significantly lower than that of consideration stage(p<0.01).
Third, when multiple regression analysis was implemented with making stage of change as a dependant variable, compared with subjects of family income of 1million won or less, those of family income of 3million won or more was a significant explanatory variable in moving to the maintenance stage when score of cons gets lower, that of self-efficacy get higher, and that of process of behavioral change gets higher.
Fourth, when covariance structure analysis was implemented for the hypothetical model, the effect of process of emotional and behavioral change on process of change of inherent variable was 0.82 and 0.98(loading matrix), respectively, which showed statistically significant and high explanatory adequacy. The effect of pros and cons, the major concepts of decisional balance, on the decisional balance, the inherent variable, was 0.89 and -0.06(loading matrix), respectively. Only in the case of pros, there was statistically significant and high explanatory adequacy, but in the case of cons, there was statistically insignificant and low explanatory adequacy(-).
The explanatory adequacy of process of change on the decisional balance, self-efficacy, and process of change, the final result variable, was plus(+), such as 0,74, 0.70, and 0.33, respectively, and statistically significant. The decisional balance and self-efficacy showed the plus correlation(0.13).
The effect of decisional balance and self-efficacy on process of change was -0.07 and 0.40, respectively, and the only effect of self-efficacy on stage of change was statistically significant.
If the exercise program, in which their own self-efficacy on the exercise can be developed by adults, and the pros of regular exercise behavior is emphasized, and which the process of behavior is emphasized as a concrete strategy for the change, are developed and practiced, it is considered that the practice rate of regular exercise of adults will be effectively improved, and it is necessary to develop the exercise program considering process of change, decisional balance and self-efficacy, shown as factors related with stage of change of adults and examine its effect.
